ANDREW MAYER, OF PHILADELPHIA, PENNSYLVANIA.

GAS-STOVE.

Specification of `Letters Patent No. 11,259, dated July 11, 1854.

T0 all whom t may concern w Be it known that I, ANDREW lMerian, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and Improved Gas-Stove; and I do hereby declare `that the following is afull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is an external view of the stove in elevation. Fig. 2, is a vertical section of the same, the plane of section being through the center;

Similar letters of reference indicate corresponding parts in the two figures. This invention relates to a new and improved stove for heating apartments by burning gas.

The nature o f the invention consists in` the peculiar construction of the stove, or the arrangement of the several parts, whereby t-he whole amount lof heat from the burning gas, is radiated or diffused in the apartment, and all unpleasant odor avoided.

To enable others skilled in the art to fully understand and construct my invention, I

`willproceed to describe it.

A, represents the body or caseof the stove, of cylindrical, or other shape, and having a bottom, B, provided with apertures or slots, (a), for the admission of air, see Fig.` 2. The lower part ofthe body or case, A, is

provided with a door, C, see Fig. l, and may also `have apertures, (Z2), through its side, covered with mica. i

D, is a tube inserted in the center of the end of the tube is trumpet shaped, as shown in Fig. 2, and has a perforateddisk, E,

within it, and also a `wire cloth screen, F;

a suitable space being between the disk and screen. The lower end of the tube, D, com municates with a gas pipe, Gr.

H, Fig. 2 isan air heating pipe, or chainber, placed vertically within the case, A, `and at its center. rIhe bottom, I, of the pipe or chamber is constructed of copper, and is a short distance above the upper part of the tube, D. The bottom, I, is larger in diameter than the upper part ofthe tube, D. The chamber, or pipe,H, communicates with the external `air at the upper part of the body, or case, A. i

J is a pipe which is connected tothe bot- `tom of the chamber, or` pipe,H. The pipe,

J, is bent, and passes between the bottom, I,

The upper and upper end of the tube, D, and passes down through one 1of the slots, (a), in the bottom, B, of the body, or case, A;

K, K, Fig. 2, are `two disks placed around the chamber or pipe, H, at suitabledistances apart. The edges of these disks are in close contact with the side of the body, or case, A; and are perforated with holes, (c) the holes in the upper ldisk being nearer the pipe r chamber, H, than the holes in the lower isk.

L, is a disk at the lower part of the tube, D. This disk extends `nearly to'the side of the body, or case, leaving a small space, sufficient for the admission of air to feed the flame. On the top of the wire cloth screen, F, is placed a quantity of pumice stone, asbestos, or other incombustible substance, see (CZ), Fig. 2.

The bottom, I, of the chamber, or pipe, H, is of copper, asbefore stated, the other parts may be constructed of iron. When it is designed to use the stove, the gas is allowed to pass into the tube, D, by turning a faucet in the pipe, Gr, and the gas is distributed, or spread over the whole surpurpose of feeding the flame, passes upward throughthe holes, (c), in the disks, K, K, and by the position of these holes, is drawn nearer the chamber, or pipe, H, as it passes `air within the chamber, or pipe H. The air last mentioned passes out of the stove at its upper part, and into a pipe, M, leading underneath the floor or into a flue. See solid arrows, Fig. 2.

The pumice stone, or asbestos, retains the "heat, and prevents the formationcf carbon,

upward, and consequently serves to heat the or lampblack, on the under surface of the copper bottom, I. To effect this perfectly, it is vnecessary that this bottom, I, be kept `near the flame, as shown in Fig. 2, in order that it may be kept hot by it. No unpleasant odor escapes into the room as it passes into the pipe,v M, at the upper part of the What I claim as new, and `desire to secure by Letters Patent, is

The arrangement of the tube, D; hot air 15 chamber, H; and disks, K, K, as herein shown and described, and for the purpose as set forth.
